Full Version: Ide Compact Flash
Linuxhelp > Support > Hardware Support
I am having problem with my Compact Flash (CF) IDE device Read/writer. I do lots of programming data to CF. The only way it works correctly is I boot the system up with a CF in the read/writer. I can program that CF and take that one out and put in another and maybe program that one. But after programming one or two more I can not program any more with out turn off the computer and starting it again. Is there a way to safely shutdown the IDU device to remove the CF and put another one in and then safely activate the device. I know this is a hot swappable issue.
are you unmounting the File systems before you pull them out? Linux isn't really "hot swappable" in the sense that you can just pull things in and out, you need to tell the system when you are doing. If you are not unmounting the media, thats your problem. If you aren't sure what I am talking about, just ask, I would be more than happy to explain. I am pretty sure this is the problem.
I am un-mounting the partitions on the device.
Problem is that Linux keep all the geometry and other parameter of the IDE devices in /proc/ide/... If CF is swapped out of the IDE reader to another CF (maybe different size) the correct Geometry info is displayed if use the command hdparm -I /dev/hd?, but the old CF that the system booted up on device info is displayed when the command hdparm -i /dev/hd?.

Is there some way to reset the CF IDE device so the Geometry info is updated to the correct info? huh.gif
